The NPs produced include ZnO, SnO₂, and CuO. Characterization was carried out using various techniques to identify the physical, optical, and chemical properties of the synthesized NPs; ultraviolet–visible spectroscopy (UV–Vis) was employed to determine absorption bands and calculate the band gaps of 2.95, 2.7, and 1.9 eV for the semiconductors (ZnO, SnO₂, and CuO). Fourier Transform Infrared (FT-IR) spectrum shows the metal–oxygen bond characteristics of the materials analyzed. The X-ray diffraction (XRD) diffractogram indicates the formation of hexagonal zincite (ZnO), tetragonal cassiterite (SnO₂), and monoclinic tenorite (CuO) structures, and crystallite sizes of 12.777, 15.451, and 39.915 nm, respectively. TEM and SEM were utilized to obtain information on surface, shape, and size; energy-dispersive X-ray spectroscopy (EDX) confirmed the chemical composition. Finally, photocatalytic studies were conducted to investigate the degradation of five organic dyes: methylene blue (MB), rhodamine B (RhB), malachite green (MG), methyl orange (MO), and congo red (CR). The results indicated that over a 180-min period, these dyes underwent degradation through a photocatalytic process, with ZnO, SnO₂, and CuO NPs serving as photocatalysts. This demonstrates that the synthesized NPs possess excellent photocatalytic properties.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 26","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10854-025-15811-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photocatalytic properties were investigated with respect to various ratios of TiO₂ to WO₃ (10:0, 7:3, 5:5, 3:7, 0:10) and heat treatment temperatures ranging from 300 to 700 °C. The combination of TiO₂ and WO₃ enhanced photocatalytic efficiency by leveraging the high photocatalytic oxidation capability of TiO₂ and the broad visible light absorption range of WO₃. The photocatalytic response was analyzed through the photobleaching of methylene blue (MB) dye and the decomposition of toluene gas. In the hybrid photocatalyst of (TiO₂–WO₃) coated on Sr₄Al₁₄O₂₅:Eu²⁺,Dy³⁺ long-lasting phosphor, the phosphor might act as an internal light source to accelerate or sustain photocatalytic reactivity, even in the absence of external light irradiation. The heterojunction of (TiO₂–WO₃) and Sr₄Al₁₄O₂₅:Eu²⁺,Dy³⁺ reduced the energy band gap and enhanced visible light absorption, thereby improving photocatalytic reactivity. The 5:5 ratio of TiO₂ to WO₃ on Sr₄Al₁₄O₂₅:Eu²⁺,Dy³⁺ showed excellent photocatalytic performance, decomposing over 80% degradation of methylene blue dye within 90 min and 67% of toluene gas within 90 min under visible-light irradiation.
